Hi Holger,
sorry for the late reply. But since no-one else replied, it doesn't seem an
important topic for the readers.

According to https://www.w3.org/TR/xmlschema-2/#integer 1000_000 is not a valid
integer literal. But it is for Python since 3.6.
The magic lxml.objectify type lookup/annotation simple does int(s) and interprets success
as "shall be interpreted as int".
One could argue that - when parsing XML data - this is not the
right/sane/intuitive choice. Or is it? :-)
<x>1000_000</x> is not an integer in the XML world.
Then we shouldn't make it one. It's unlikely that data gets passed through
XML in Python syntax. We have the same for "True" and "False", which come
out as str, not bool. And this applies to FloatElement as well, which uses
float() as parser and thus also supports "_" in Py3.6+.
I'll see what I can come up with.
